Mini-Calendar can link items in a SharePoint list, List Rollup, or Business Connectivity Service (BCS) data source to a compact calendar view.
Before you can use Mini-Calendar, you need to add it to a SharePoint wiki page using the instructions here.
NOTE: If you are adding the web part to a web part page, follow the instruction here.
To configure Mini-Calendar to display SharePoint list items, modify the web part properties and configure the required data source settings and configuration options as described in the topics linked below. Without configuration, Mini-Calendar displays dates like a standard out-of-the-box SharePoint calendar.
